Hi. Many photos that I scan have something written on the back. Scanning the back too is easy enough. But as far as I know, no photo cataloging software (iPhoto, Aperture, etc.) has ever had a feature to pair the photo with the back of the photo. I use Aperture. Anyone know if any way to cleverly way to get Aperture to accomplish that? I suppose I could create an album for each pair (consisting of the front and back) but that's a lot of albums. Is there a better way? Maybe stacks?
